Best lame settings for 64/22 audiobook files?

2002-02-26 18:57:08

I've been using the Radium hacked FhG so far on 192 kbit and now that I'm ripping some of my audiobooks (few of which are mono) for my portable player I'm trying LAME for the first time to encode them using VBR around 64 kbit. Could anyone list the 'perfect' parameters for audiobooks that should result in ~ 64/22 files?

What I'm asking, is there some kinda reference setting like 'lame --r3mix' for audio files of this type? TIA! As well, is there a thorough explanation of the LAME paramters around that is more for newbies than the one that comes with it? 

Thanks!

I would use --alt-preset 80, which will result in ~80/32 files. Maybe a little more than you need, but you'll get some of dibrom's custom tweaks. For limited-bandwidth audio books, it should sound rather good. There may also be an experimental "voice" setting available, but if you can live with 80kbps files, the --alt-preset 80 switch should serve you well for this application.

For lowbitrate audiobooks (stereo), one might want to experiment with Takehiro's new inter-channel masking: --interch X (X is a float value)
Latest Lame 3.92alpha is needed.
Something like: --interch 0.005
It makes stereo separation a bit worse, but may otherwise increase quality.
I would probably still choose some FhG codec for lowbitrate coding though..

why use a hifi tuned codec ?? itsj ust wasete of bit

i woudle go with acelpt.net which comes with MS media encocder 4.0 and newer

it uses bitrates at aorund 8-16kbits
and gives very clear voice.


this codec is optimized for voice only and low bitrates
